ATTACHMENT FOR TYPE-WRiTlNG MACHINES.

SPECIFICATION forming part of Letters Patent No. 387,752, dated August 14, 1888.

Serial No. 251,011. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES W. Tnaynn, of Collinsville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Attachments for TypeWVriting Machines, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

The object of my invention is to provide an attachment that may be readily applied to the frame of a typewriter for the purpose of holding and guiding the sheet of paper in such manner as to allow the sheet to be written upon to the extreme bottom.

My invention is more especially applicable to the so-called Hammond Type-Writer, and in the accompanying drawings a form applicable to such a machine is shown.

My improvement consists in a guide composed of rods or rolls held by clamps that are provided with means for adjustably securing them to the carriage of the machine, so as to hold the sheet of paper in place to be written upon by the types after it has passed beyond the grasp of the regular feed-rolls of the machine; and. it further consists in details of the several parts of the device and their combination, as more particularly hereinafter described, and pointed out in the claims.

Referring to the drawings, Figure 1 is a detail front view of the paper-rack of a Hanr mond type-writer with my improved attachment. Fig. 2 is a detail view in vertical sec- 5 tion through the rack, my attachment, and the paper-feed rolls. Fig. 3 is a detail plan View of the parts shown in Fig. 1, with portions cut away to show construction.

In the accompanying drawings, the letter a denotes the guide as a whole, made up of the clamps 7) and the rods 0. The clamps are made with sockets to embrace the standard d of the paperrack (Z on the machine, and the project ing parts of the clamp have an upturned 5 socket, in which are laid the ends of the rods 0 orequivalentgnides. Ascrewpassingthrough the body of the clamp into one of the sockets serves as a means for securing the clamp to the paperrack of the machine, while the thumb screwsfserve to clamp the rods in place. In order to provide means for holdingthe guiderods in proper position over the feed-rolls of the machine, I provide a key, g, which is made of a thin piece of metal adapted to grasp the covering-plate on the top of the carriage, and having a slot, 5/, in its edge, that receives and holds the upright of the paper-rack. The po sition of the slot 9 along the edge of the key g determines the angle at which the paper-rack shall stand.

In using my device the upper edge of the sheet being printed upon is passed through the guides between the rods, and is held there more or less securely by the tension of the clamp-screws upon the rods at their opposite ends.

Although my improvement is shown and de' scribed with reference to one particular class of type-writing machines, it may evidently be adapted for use upon other kinds without material change, and I do not limit myself to its use upon any particular machine.

I claim as my improvement I. In combination with the carriage of a type-writing machine, a supplemental paperguide composed of the clamps, in combination with the parallel barssupported by the clamps, and the clamp screws whereby the clamps and the rods are held in position, all substantially as described.

2. In combination with the paper-carriage, the key 9, having a socket adapted to hold the upright of the paper-rack, the paper-rack, the

clamps adjustably secured thereto, and the bars held by the clamps in position to support and guide the paper, all substantially as described.
